Interpreting Cement Science. Cement and concrete materials science is a multidisciplinary subject, involving engineers, geologists, chemists, physicists and many others. This website is for the great majority of us who aren''t university professors of cement chemistry but whose work requires a good understanding of the subject.
A mixture with an excess of cement paste will be easy to place and will produce a smooth surface; however, the resulting concrete is not costeffective and can more easily crack. Portland cement''s chemistry comes to life in the presence of water. Cement and water form a paste that coats each particle of stone and sand—the aggregates.
